摘　　要：水箱液位变化过程具有非线性、时变性和不确定性,采用传统的控制理论与方法很难获得较满意的动态性能和稳态响应;基于常规模糊控制系统可以实现水箱液位的稳态控制,但常规模糊控制系统存在动态性能不足和稳态响应时间长等问题。针对以上问题,设计了一种非对称模糊控制系统用于水箱液位的控制。通过仿真实验,验证了非对称模糊控制系统可获得良好的动态响应,同时在稳态收敛时间上优于常规的模糊控制系统,从而证明了该方法的有效性和优越性。The process of change in water tank level is nonlinear, time-variable and uncertain. Using the traditional control theory and method is difficult to obtain satisfactory dynamic response and steadystate accuracy. Basing on conventional fuzzy control system can achieve stability of the water tank level control, but the conventional fuzzy control systems lacks the presence of dynamic performance and its steady-state response time is too long. For these problems, this paper has designed a non-sym- metric fuzzy control system for water tank level control. Through the simulation of the same controlled object, the non-symmetric fuzzy control system obtains a good dynamic response and convergence time, which proves that this method is effective and superior compared with the conventional fuzzy control system.
